Audio Watermarking Using DC Level Shifting - Uludag, Arslan (2001) (Correct)
....is desired. This requirement necessitates the utilisation of human sensory models (HVS: Human Visual System, HAS: Human Audible System. and characteristics in watermark embedding process. More information about watermarking in general and audio watermarking can be found at [3] 4] 5] 6] [7] and [8] 2. TERMINOLOGY Several techniques related to digital watermarking are: Steganography relies on embedding the secret information in unsuspected data and generally used in secret point to point communication between communicating parties. This technique is not robust to attacks. ....

Computing the Probability of False Watermark Detection - Miller, al. (1999) (4 citations) (Correct)
....a watermark detector. The input media is first processed byawatermark extractor which generates an n dimensional extracted vector, V . Examples of watermark extraction include various combinations of spatial registration [8] frequency transforms [9,10,11] blockaveraging [12,13] spectral shaping [14,15], whitening [16] and subtraction of the unwatermarked original media [9, 17] Reasons for applying these processes include the following: increasing robustness to certain common types of attack, increasing signal to noise ratio, reducing the size of data to make detection cheaper, and generating ....

....first nonlinearly combined with an audio signal to spectrally shape it and the resulting signal is then high pass filtered prior to insertion into the original audio signal. Because of the high pass filtering, the method is unlikely to be robust to common signal distortions. However, Preuss et al. [43] describe an improved procedure that inserts the shaped watermark into the perceptually significant regions of the audio spectrum. The embedded signaling procedure maps an alphabet of signals to a set of binary PN sequences whose temporal frequency response is approximately white. The audio signal ....
....of Fourier coe# cients and therefore argue that such an approach should be more robust to tampering as well as to changes in image contrast. The inserted watermark is independent of the image and is recovered using traditional correlation without the use of the original image. Several authors [43, 33, 34, 7, 8, 13, 14], draw upon work in spread spectrum communications. Smith and Comiskey [15] analyze watermarking from a communications perspective. They propose a spread spectrum based technique that predistorts the watermark prior to inserting. However, the embedded signal is not a function of the image, but ....
